Public Speaking Tip and Cell Phones
Presentation Tip: Stay calm if people have their cells phones out and seem to be texting. Many people use their cell phones for taking notes.
I recently had an attendee thank me for for my presentation and said he was using his cell to take notes...he wanted to make sure I was aware the reason he was using his cell and truly valued my session.
I now announce "please turn your cell phones off (or on stun mode) during my session unless you will be using for note taking." And yes, some will still use for texting. :-)
